|
|
|
46 ---------------------------
|
|
|
47
|
|
|
48 -- GNAT requires that there be a one to one correspondence between source
|
|
|
49 -- file names (as used in the Osint package interface) and unit names as
|
|
|
50 -- defined by the Uname package. This correspondence is defined by the
|
|
|
51 -- two subprograms defined here in the Fname package.
|
|
|
52
|
|
|
53 -- For full rules of file naming, see GNAT User's Guide. Note that the
|
|
|
54 -- naming rules are affected by the presence of Source_File_Name pragmas
|
|
|
55 -- that have been previously processed.
|
|
|
56
|
|
|
57 -- Note that the file name does *not* include the directory name. The
|
|
|
58 -- management of directories is provided by Osint, and full file names
|
|
|
59 -- are used only for error message purposes within GNAT itself.
